2A/4A/15A/25A EMI Power Filter Board Anti-interference AC Power purification

Description

Details：
EMI power filter circuit introduction: The circuit consists of three parts, the first part is a differential mode filter part, the second part is a common mode filter circuit, and the third part is insurance, equipped with a fuse holder. Different fuses can be replaced. Internal circuit of two-stage compound EMI filter Due to the use of two-stage (also known as two-section) filtering, the effect of filtering noise is better For some user sites, there is a problem of fast transient group pulse interference with a repetition frequency of several kilohertz, which can inhibit The shortest design of high current line, short path, can withstand larger current, and less interference to the outside world PCB size: FR4 83X42X1.6MM Common mode inductors have four specifications: 2A, 4A, 15A ，25A, This module can be used with a decoder or a power amplifier to filter high-frequency noise of the power supply, eliminate mains interference, and purify the power supply, which can significantly improve the sound quality of the power amplifier, enhance the resolution and make the background quiet. The input GND needs to be connected to the ground wire of the power cord, and can also be connected to the chassis shell
